By comparing quantitative ranking with qualitative contributions, we reveal that academic assessment has to put real contributions ahead of quantitative indicators and that rankings have nothing to do with universities’ and their libraries’ true values. The greatness of a university lies in its impacts on the progress for human knowledge and the promotion for social development. Although ranking of universities by way of quantitative indicators can reflect some information, we should pay more attention to qualitative contributions.

Background: In combat operations, patients with traumatic injuries require expeditious evacuation to improve survival. Studies have shown that long transport times are associated with increased morbidity and mortality. Limited data exist on the influence of transport time on patient outcomes with specific injury types. The objective of this study was to determine the impact of the duration of time from the initial request for medical evacuation to arrival at a medical treatment facility on morbidity and mortality in casualties with traumatic extremity amputation and noncompressible torso injury(NCTI).Methods: We completed a retrospective review of MEDEVAC patient care records for United States military personnel who sustained traumatic amputations and NCTI during Operation Enduring Freedom between January 2011 and March 2014. We grouped patients as traumatic amputation and NCTI(AMP+NCTI), traumatic amputation only(AMP),and neither AMP nor NCTI(Non-AMP/NCTI). Analysis was performed using chi-squared tests, Fisher's exact tests,Cochran-Armitage Trend tests, Shapiro-Wilks tests, Wilcoxon and Kruskal-Wallis techniques and Cox proportional hazards regression ***: We reviewed 1267 records, of which 669 had an injury severity score(ISS) of 10 or greater and were included in the analysis. In the study population, 15.5% sustained only amputation injuries(n=104, AMP only), 10.8% sustained amputation and NCTI(n=72, AMP+NCTI), and 73.7% did not sustain either an amputation or an NCTI(n=493,Non-AMP/NCTI). AMP+NCTI had the highest mortality(16.7%) with transport time greater than 60 min. While the AMP+NCTI group had decreasing survival with longer transport times, AMP and Non-AMP/NCTI did not exhibit the same ***: A decreased transport time from the point of injury to a medical treatment facility was associated with decreased mortality in patients who suffered a combination of amputation injury and NCTI. No significant association between transport time

背景：几项小型临床试验提示雌激素替代疗法可能有助于女性Alzheimer病（AD）患者的治疗。　　目的：确定雌激素替代疗法能否改善轻到中度女性AD患者总体功能、认知或日常生活能力。　　设计：Alzheimer病协作组于1995年10月至1999年1月进行的一项随机、双盲、安慰剂对照临床试验。　　参加单位：美国32个研究中心。　　受试对象：总共120例轻到中度女性AD患者。细微精神状态检查评分介于12～28分间，既往已行子宫切除术。　　干预：受试者随机服用雌激素0.625 mg/d（n=42）、1.25 mg/d（n=39）或者剂型相同的安慰剂（n=39）。1例患者于随机后接受药物治疗前退出试验；97例完成试验。　　主要结果评定：主要结果评定指标为临床整体印象的改变（CGIC），分值为7分，采用意向治疗(intent-to-treat)分析。次要指标包括其他总评估以及情绪、特殊认知功能（记忆、注意力和语言）、运动功能和日常生活能力；于随访 2、6、12和15个月时，对雌激素组与安慰剂组进行比较。　　结果：雌激素组与安慰剂组CGIC评分为5.1比5.0 (P=0.43)；雌激素组80%的患者恶化，而安慰剂组74%恶化(P=0.48)。除临床痴呆评分提示雌激素组恶化外(雌激素组与安慰剂组相比治疗后平均变化为0.5比0.2，P=0.01)，两组次要结果指标无显著差异。　　结论：雌激素替代治疗1年不能延缓轻、中度女性AD患者病情的进展，整体功能、认知和功能预后亦无改善。研究结果不支持雌激素对这种疾病有治疗作用的结论。雌激素对AD的潜在预防作用尚需进一步研究。
